A transportation system that provides full accessibility results in a high quality system for all users. Accessible infrastructure has been linked to increased business opportunities, social development health benefits, and increased independence among community members.

Accessible design practices incorporate the needs of people with disabilities into the design and development of public infrastructure, allowing facilities to be accessed independently by people with disabilities. ​

ADA requirements are integrated into all Oregon Department of Transportation standard drawings, details, specifications and design manuals. In addition, ODOT prepares guidance and element designs to maximize accessibility in new construction and existing facilities. Technical guidance documents clarify when, where, and how to provide access in the many unique situations found along the state highway system.​

Project Elements that Impact ADA Accessibility

For each project element, technical requirements are provided to guide the design of accessible public facilities. Project requirements for ADA can be found in the ADA Curb Ramp Process document.

​When curb ramps are included in a project, ODOT requires several processes to ensure the constructed curb ramp will comply with accessibility requirements. The processes are summarized in the ODOT ADA Curb Ramp Process document.

Design shall meet criteria in the ADA Curb Ramp Design Checklist,

Design detail sheet shall be provided for each corner, and

Constructed curb ramps must be inspected using an ODOT curb ramp inspection form to document compliance with accessibility requirements.

The TPAR details how pedestrians will be directed through or around a work zone. The level of detail required for the TPAR depends on the complexity of the project and the volume of pedestrian traffic.
